Umbilical arterial (UA) Doppler assessment is used in surveillance of fetal well-being in the third trimester of pregnancy. Abnormal umbilical artery Doppler is a marker of uteroplacental insufficiency and consequent intrauterine growth restriction (IUGR) or suspected pre-eclampsia.
The Fetal Doppler uses ultrasound technology to bounce sound waves off the baby and return a representation of the fetal heartbeat. Some specialized devices can be used as early as eight weeks., though 12 weeks into pregnancy is a more normal time frame. The sound is usually that of galloping horses.
